Title: Control signal detection system
Inventor: UENO HIROAKI
IPC: G11B15/087
Filed: 1978-08-22
Abstract: PURPOSE:To avoid the effect of the dropout by detecting the bit section signals recorded in pile on the signals and the bit signals between the section signals and the memorizing the necessary bit number time. CONSTITUTION:When the heading of the sectioned data of the magnetic recording medium is detected by heading detector 25, FF1 is set by the heading detection pulse to open AND gate G1. Thus bit data signals DB1, DB2 and so on forming four bits and others are detected along with signals DH1 and DH2, bit section signal DH1 plus data start signal DS to be turned into the control signals through rectifier 27, waveform shaper 29 and others to trigger monostable multivibrator MM1 via OR gate G2. As a result, MM1 generates the pulse featuring the time longer than the time of one bit and shorter than the time of three bits to open AND gate G4, and FF2 is set by the detection signal passing through gate G1. Thus FF2 memorizes the time until detection of the next signals DH1, and accordingly the control signals are detected substantially via register RG and others at the fixed time even in case no signal DH1 and others is detected through dropout.

SOLUTION: A starting material contg. Al and Mg is evaporated with thermal plasma in an oxygen atmosphere. Preferably an arc discharge is caused between an electrode comprising an Al-Mg alloy or based on the alloy and a counter electrode in a state that protects the latter electrode with an inert gaseous stream and allows the stream to orient toward the former electrode to generate a plasma flame. The Al-Mg alloy is evaporated with the plasma flame and an oxygen-contg. gas is introduced and brought into contact with a vapor stream generated in the plasma flame and/or on the downstream side of the plasma flame.

Abstract: PURPOSE:To prevent a rapid change of engine speed, by providing a switch, which stops hysteresis action when engine temperature becomes above a prescribed level, to an ignition device having the hysteresis action in which an ignition start speed is different from an ignition reset speed. CONSTITUTION:At high speed operation of an engine, a transistor 22 charges and discharges a capacitor 23 to ignite an SCR4 through a Zener diode 24. Simultaneously with this time, a hysteresis circuit 9 is operated, and a transistor 25 is conducted to flow an electric current bypassing a resistor 18, while an operating level of a transistor 15 is changed to decrease a conduction width of the transistor 22, and the ignition is not reset unless a speed of the engine becomes lower. When an engine temperature thermo switch 10 is operated, the transistor 25 is cut off, and as the operating level of the transistor 15 decreases a transistor 27 is turned off through a diode 26, then the hysteresis circuit is not operated. In this way, a rapid change of engine speed at a high load can be prevented.

IPC: G11B5/09
Filed: 1982-06-15
Abstract: PURPOSE:To detect a zero cross, by obtaining an exclusive OR between a signal obtained by giving a delay of a prescribed period to the code bit signal of a digital information signal of plural bits synchronizing with a clock signal and a signal of the code bit which received no delay. CONSTITUTION:The digital information signals are supplied to input terminals I0-I3 synchronously with a period of a cynchronizing signal. The code bit signal of the information signal supplied to the input terminal I3 is supplied to the terminal of one side of an exclusive AND circuit 22 as well as to the other terminal of the circuit 22 with a delay of a period of the synchronizing signal given by a D type FF21. The circuit 22 delivers L or H level in accordance with the coincidence or dissidence of both inputs. Thus the FF21 works together with the circuit 22 to detect a change (digital zero cross) of the code bit. When H and L levels are supplied to T1 and T2 respectively from a muting operation circuit, FF17 and 18 are set at H level. Thus signals O0-O3 producing no unpleasant sounds are delivered in response to inputs I0-I3.
